By fo :u f. the cassitioned between the trackways carried by the ings from sheet metal and from. sections detachcasing as desired. ably connected, it is obvious that if the owner A further object is to provide an automobile abandons a particular station the pit y be dipit having a plurality of trackways extending vided into its sections, removed from the ground 5o across the same with a drain tank having e, drainand transported to a new location, which is not 50 age device which drainage device may be shifted possible with pits as at present constructed of to various positions between either or both of concrete, which can not be transported, and must :the traclsways as desired. be destroyed or left, which is a terial loss to the With the above and other objects m view the operator, when it is considered that in some serv- 5 5 invention resides in e coination and ar= ice stations there are as m as twenty or thirty 55 of these pits, for instance those serving taxicab companies. The lower rectangular shaped frame 5 is provided with transversely disposed brace bars 10, which brace the casing section 5 transversely and prevent collapse incident to pressure of dirt on the sides thereof. Brace bars 10 have connected thereto upwardly extending standards 11, which standards are connected by means of angle members 12 to the undersides of the channeled track members 13, which extend across the upper side of each casing. Each casing is provided with two pairs of trackways 13 for receiving two machines at the same time, and at the same time the operator will have access to the undersides of both machines without leaving the pit, and where a plurality of units are connected together will have unobstructed access through the entire pit, which is not only desirable for eliminating the necessity of the operator coming out of the pit to go to another pit, but allows the operator to easily escape from the pit in case of fire, as it will only be necessary for the operator to go into the adjacent casing and leave the pit by way of the steps 14.

It will be noted that the trackways at the side of each casing extend beyond the sides thereof substantially for half theirr width, therefore it will be seen that when an adjacent section is desired, it will only be necessary to extend the side of the adjacent section under the trackways 13 referred to, and secure them in place by means of the bolts 9 as clearly shown in -Figure 5, and after which the deflecting flanges may be connected. The adjacent flanges of the adjacent trackways d 13 are connected together by U-shaped upwardly extending flanges 15 as clearly shown in Figures 1 and 2 and which flanges are sufciently high tu prevent an automobile from going over the same, consequently danger of an automobile running into the pit is.obviated. The U-shaped member centrally of each casing is provided with arms 16, which extend entirely across the casing, thereby obviating any danger of lateral movement of the automobile on either of the trackways in one dlrection, and the outer anges of the outer trackways are provided with similarly constructed flanges 17 for the same purpose. A removable platform 18 is provided between the flanges 16 and onto which platform or walkway, the operator of the automobile may have access to the machine or may use the same when leaving the machine. Imbedded in the grou'nd, preferably below the pit and casing is a waste oil tank 19 -from which a pipe 20 extends upwardly substantially centrally of the chamber of the casing, and

pivotally connected on the threaded upper end 21 of pipe 20 is a horizontally disposed arm 22 having pivotally connected thereto by the union 23 a second horizontally disposed pipe 24, which pipe 24 terminates in a vertically disposed pipe 25 in which is slidably mounted and vertically movable the tube 26 carried by a funnel 27. By providing the pivoted pipe sections 22 and 24 it will be seen that the funnel 2'1 may be positioned beneath either of the trackways as desired and where there are automobiles on both trackways, the operator may drain one machine while working on the other. It will also be noted that by providing the arms 22'and 24, the funnel may be placed in various positions beneath an automobile on either trackway, consequently the device may be easily and quickly adjusted to a position where oil and grease drained from the machine will pass through the piping to the tank 19, from which it may be removed through a dischargel pipe 28, for instance by pumping, however a gravity drain may be utilized if desired. The tubular member 26 has slidably mounted thereon a collar 2'9, which is provided with a set screw 30, and by loosening said set screw 30, it is obvious the operator can easily and quickly move the funnel 27 upwardly between either trackway 13 to a position adjacent the engine of an automobile or any other part thereof, thereby obviating splashing of grease or oil drained from the machine. After the adjusting operation the set screw 30 is tightened, thereby preventing downward movement of the tube 26, and causing the collar 29 to hold the tube and the funnel against downward movement by engagement with the upper end of the pipe section 25.

From the above it will be seen that a service station pipe casing is provided which may be easily and quickly removed from the ground and transported to another location and that said casing is provided with means whereby additional casing sections may be added to opposite sides thereof as desired.

The invention having been set forth what is claimed as new and useful isz- 1. A multiple automobile pit comprising a single common chamber, a plurality of spaced track- Ways overlying a plurality of individual servicing positions in said common chamber and bumper means at the front end of said trackways for guiding the wheels of automobiles thereto.

2. A multiple automobile pit comprising a single common chamber, a plurality of spaced trackways overlying a plurality of individual servicing positions in said chamber, a plurality of walkways interposed between the said trackways and bumper means between the individual tracks of each trackway and between adjacent trackways.
